MECHANICAL REFRIGERATION.

Application filed June 3,

My invention relates to mechanical refrigeration and particularly tomeans for dispos ing of the drain from the refri erated portions of amechanically refrigerated refrigerator cabinet, and the principal objectof my invention is to provide new and improved means of this type. Inthe drawings the single figure is a view through a compressorcompartment of a self-contained mechanical refrigerator cabinetillustrating one embodiment which my invention may assume.

The embodiment of my invention herein shown comprises a refrigeratorcabinet 11 provided with a compressor compartment12 containing acompressor 13 operated through a belt 14 by an electric motor 15, havingits inlet connected to expansion means dis osed within the refrigeratingsection of the ca inet 11, and having 1ts outlet connected by means of aconnection 16 to the inlet of a condenser 17 disposed within thecompressor compartment 12 and having its outlet connected to the inletend of the same expansion means.

Extending into this compressor compartment 12 is a duct 18 arranged tocarry away fluid collecting inlthe refrigerated portions of therefrigerator cabinet 11 and herein shown as terminating in a position tocause the conveyed fluid to flow into an annular receptacle 19 formedsurrounding and integral with the up r portion of the compressor 13 sothat the eat of the compressor 13 is a plied to and effective toevaporate the fluid entering the receptacle 19 from the duct 18 to thuseliminate the necessity for either a drain connection fromtherefrigerator cabinet 11 or a drain pan below the refrigerator cabinet 11requiringperiodic emptying.

Fr the abdvj,e description it will be obviousfi'i -thos'e skilled in theart that I have provided new and improved means for dis posing of thefluidcollecting' in the refrigerated portions of a mechanicallyrefrigerated refrigerator cabinet. At the same time, it will also beobvious to those skilled in the art that the articular embodiment of myinvention i herein shown and described maybe variously changed andmodified without departing from the spirit of my invention orsacrificing 1926. Serial No. 118,471.

the advantages thereof, and it will therefore be understood that thedisclosure herein is illustrative only and that my invention is notlimited thereto.

I claim:

1. In a mechanical refrigerator unit, in combination with a cabinethaving a refrigerating chamber and means to catch and collect and conveyaway liquid from said chamber, refrigerating mechanism disposedexteriorly of said chamber and of a type having a compressor which givesoff heat, and receptacle means arranged to receive such liquid andpositioned exteriorly of said refrigerating chamber in intimate thermalrelation with said compressor to receive heat therefrom.

2. In a mechanical refrigerator unit, in combination with a cabinethaving a refrigerating chamber and means to catch and collect and conveyaway liquid from said chamber, refrigerating mechanism disposedexteriorly of said chamber and of a type having a compremor which givesoff heat, and receptacle means arranged to receive such liquid andpositioned encircling said compressor to receive heat from saidcompressor.

3. In a mechanical refrigerator unit, in combination with a cabinethaving a refrigerating chamber and means to catch and collect and conveyaway liquid from said chamber, refrigerating mechanism disposedextcriorly of said chamber and of a type having a compressor which givesoff heat, and rece tacle means arranged to receive such liquid andsecured to said compressor to receive heat from said coin ressor.

4. In a mec anical refrigerator unit, in combination with a cabinethaving a refrigerating chamber and means to catch and collect and conveyaway liquid from said chamber, refrigerating mechanism disposedexteriorly of said chamber and of a type having a compressor which givesoff heat, and re ceptacle means arranged to receive such liquid andintegral with said compressor to receive t:
